| MITSUBISHI (OPTICAL DEVICES) FU-427SHL-8M22 1.3 mm LD MODULE WITH SINGLEMODE FIBER PIGTAIL DESCRIPTION Mod ule type FU-427SHL-8M22 has been developed for coupling a sin glemode optical fib er and a 1.3 mm wavelength InGaAsP LD (Laser diode). FU-427SHL -8 M22 is suitable to light source for measurning instruments(especially, OTDR). FEATURES High optical output power Emission wavelength is in 1.3 mm band MQW* active layer FSBH** structure fabricated by all MOCVD process *Multiple quantum well **Facet selective-growth buried heterostructure APPLICATION OTDR ABSOLUTE MAXIMUM RATINGS Parameter Laser diode Reverse voltage Forword current Operating case temperature Storage temperature (Tc=25 C) Symbol Vrl Ifl Tc Tstg Conditions Pulse(Note 1) Rating 2 1 -20~+60 -40~+70 Unit V A C C Note 1.
